Forward biased base-collector junctions only happen [in common emitter circuits] when the transistor is saturated, and the voltage across emitter-collector is about 0.2V Report comment Reply ...

Collector current = Emitter current – Base current = 100mA – 2 mA =98 mA Base current = Emitter current – Collector current = 100mA – 98mA = 2 mA. The condition is just reversed in the case of a PNP ...

5. Power-supply rail with a 1-µF cap connected from V CC to GND.. Amplifier Circuit. The common emitter amplifier and emitter follower will be demonstrated using the same amplifier circuit.

BJTs are made of doped materials and can be configured as NPN and PNP. A transistor is an active device with three terminals, and these three terminals are known as the Emitter (E), the Base (B ...

Shown below is a typical PUT Oscillator circuit where two discrete transistors are employed to emulate the PUT. The voltage on the emitter of the PNP transistor in this oscillator circuit ... The ...

Manufacturing companies, particularly those that mass-produce electronic circuits, work pretty much around bipolar junction transistors, like PNP and NPN. However, choosing between these two BJTs ...

Then, most transistors that would do high voltages had terrible Hfe – so the common emitter input id the current gain and biased the HV-but-otherwise-crappy output transistor. And yes, of course ...
